Hi bashnaini,Try looking at Swisscom's "Pocket Connect". This provides you with your own wifi hotspot which you carry round with you. It's a bit smaller than a smartphone and, of course, you need to own phone set to wifi to access it. Back in July the minimum "hire" was for 5 days for about CHF35. There aren't many places where you can collect but when you're finished you simply put it in a post box.Andrew
